Study of DNA packing by a cationic lipid DSTAP by Magnetic tweezers (MT) (CAT#: STEM-MB-1268-WXH)

Introduction

DNA packaging is the folding of an organism's DNA into a compact structure that can fit within the nucleus of a cell.
DSTAP chloride (1,2-distearoyl-3-trimethylammonium-propane chloride) is a cationic lipid with a variety of potential applications, including transfection and drug delivery.




Principle

Magnetic tweezers (MT) are scientific instruments for the manipulation and characterization of biomolecules or polymers. These apparatus exert forces and torques to individual molecules or groups of molecules. It can be used to measure the tensile strength or the force generated by molecules.

Applications

Study of mechanical properties of biological macromolecules like DNA or proteins in single-molecule experiments.
Study of the rheology of soft matter.
Study of force-regulated processes in living cells.

Procedure

1.Sample preparation
2.Force Calibration
3.Measurement
4.Analysis
